Since 18 years, wind power plants in Germany are being promoted by guaranteed feed-in tariffs. As a consequence, the supply of electricity from wind power plants is steadily increasing. Meanwhile, the market price for electricity starts exceeding feed-in tariffs within certain periods in the course of the day. This report examines whether this can be inter-preted as a first signal of commencing marketabil-ity of wind power. If so, the study further investi-gates implications for the promotion of renewable energies in Germany. In a first step, the market potential of wind power in Germany is being assessed. In order to derive a representative estimation, average electricity prices on the spot market, average amounts of produced wind power as well as the actual wind power portfolio in Germany is being considered. Based on this estimation, the study further derives a flowchart in order to account for the various requirements, both on the side of wind producers as well as on the side of grid operators. Finally, further developments in the promotion of wind power in Germany are being elaborated. In the long run, a significant increase in the direct sale of wind power can be expected. In order to promote new strategies and schemes to efficiently feed this electricity into the grid, an early promo-tion of direct sales may be reasonable. For this purpose, a combination of guaranteed feed-in tariffs and premiums on top of the market price may be suitable.
